Conditions
Brief summary
The aim is to develop a food supplement drink that supports muscle health by combining specific fatty acids, which can positively affect metabolic and inflammation processes that are important for muscle health.
Detailed description
This study will assess the effects of a vegan nutritional formulation containing caprylic acid and omega-3 fatty acids on recovery from muscle-damaging exercise. The goal is to determine whether this supplement can mitigate muscle damage, reduce inflammation, and accelerate functional recovery, thereby supporting long-term muscle health and functional independence. This research has the potential to reveal a novel approach to muscle health management, contributing to the development of safe and effective nutritional strategies that support healthy aging.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in isometric muscle strength of the vastus lateralis muscle on a muscle dynamometer before and 72h after damaging exercise | The change in muscle strength will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The main study endpoint is the change in skeletal muscle function recovery from a single bout of damaging eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids, compared to a control emulsion, from before exercise (t=0) to 72 hours post-exercise. Skeletal muscle function will be measured as maximal voluntary isometric muscle strength of the vastus lateralis muscle on a muscle dynamometer. The maximal voluntary strength is expressed as maximal voluntary contraction (Newtons). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in muscle fatigue from before until 72 hours after damaging exercise measured with electrical stimulation on a muscle dynamometer | The change in fatigue resistance will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The change in muscle fatigue recovery from a single bout of damaging eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids compared to a control emulsion will be examined by means of a two-minute fatigue inducing protocol on a skeletal muscle dynamometer. Every other second during two minutes, electrically induced muscle contractions will be evoked on the vastus lateralis muscle at 40% of the maximal voluntary muscle strength. The percental decline in muscle force (N) generating capacity will be monitored as indicator of fatigue resistance. |
| Change in muscle soreness from before until up to 72 hours after a damaging exercise using a VAS-Scale and soreness questionnaire | The change in muscle soreness will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The change in muscle soreness from a single bout of eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids, compared to a control emulsion will be measured by means of a VAS-Scale, measuring current muscle soreness, as well as a retrospective pain questionnaire, measuring muscle soreness over the preceding 24 hours. |
| Plasma creatine kinase concentrations before and up to 72 hours after damaging exercise in blood | The change in plasma creatine kinase will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The change in creatine kinase concentrations from a single bout of eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids, compared to a control emulsion, will be measured using commercially available kits. |
| Plasma cholesterol concentrations before and up to 72 hours after damaging exercise in blood | The change in plasma cholesterol concentrations will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The change in plasma cholesterol concentrations from a single bout of eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids, compared to a control emulsion, will be measured using commercially available kits |
| Plasma triglyceride concentrations before and up to 72 hours after damaging exercise in blood | The change in plasma triglycerides will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The change in plasma triglyceride concentrations from a single bout of eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids, compared to a control emulsion, will be measured using commercially available kits. |
| Plasma beta-hydroxybutyrate concentrations before and up to 72 hours after damaging exercise in blood | The change in plasma beta-hydroxybutyrate will be measured at time points 0 hours (before exercise), and post exercise, and at 24 hours, 48 hours and 72 hours post exercise. | The change in plasma beta-hydroxybutyrate concentrations from a single bout of eccentric exercise between an emulsion containing caprylic acid and omega 3 fatty acids, compared to a control emulsion, will be measured using commercially available kits. |
